[sheepdog] [PATCH 4/9] sheep: exit program when EIO occurs

[MORITA Kazutaka]

When EIO occurs, a sheep is expected to become a gateway node, but it
doesn't work now.  To fix this, we need to support changing virtual
nodes without stopping sheeps.  This patch makes it a future work, and
stops the program simply on the EIO error.
